Definitions

  • photosensitive elements comprising a support and a photosensitive layer provided thereon.
  • Background of the invention Photosensitive elements are used in image- reproduction processes and are well-known in the graphic arts industry. These elements are usually exposed to actinic radiation through an image-bearing transparency, such as a color separation transparency, to produce an image which is either a positive or negative with respect to the transparency used.
  • Positive-working photosensitive elements are described in Chu and Cohen, U.S. Patent No. 3,649,268 and negative-working
  • tonable elements It has been found that greater color flexibility can be attained from tonable elements.
  • the operator can mix the toners supplied by the manufacturer as desired, and thus, toned images with an almost unlimited variety of colors can be prepared. Instead of many specialty films, the manufacturer need only supply a single, non- colored, tonable element. Following imagewise exposure, tonable

  • the invention describes a process for forming a colored image comprising the steps of:
  • photoinsolubilizable, photosensitive composition comprising a
  • a water-soluble plasticizer wherein said photosensitive material is present in sufficient amount to insolubilize said photosensitive layer on exposure to actinic radiation, said photosensitive composition is present in sufficient amount to form a layer when said photosensitive layer is coated, and said plasticizer is present in sufficient amount to make said photosensitive layer tonable;
  • step (C) applying a colorant to the photosensitive layer; wherein step (A) is carried out before step (B).
  • Step (C) may be carried out before step (A), between steps (A) and (B), or following step (B). In a preferred embodiment, step (C) is carried out between steps (A) and (B).
  • the aqueous- processable photosensitive material is selected from the group consisting of photosensitive, aqueous-processable polymeric diazo resins; photosensitive, aqueous- processable bis-azides; and photosensitive, aqueous- processable derivatives of polyvinyl alcohol wherein said polyvinyl alcohol derivative comprises
  • the invention describes a tonable, photosensitive element comprising a solid, tonable, aqueous-processable photosensitive layer and a support and a process for forming a colored image from such an element.
  • photosensitive composition comprising a photosensitive material and a water-soluble plasticizer could be applied to a support to produce a water-developable, photosensitive element which is then toned to provide color.
  • the photosensitive material insolubilizes the photosensitive composition on exposure to actinic radiation.
  • Preferred photosensitive materials include (1) polymeric diazo resins; (2) bis-azides; and (3) derivatives of polyvinyl alcohol wherein the polyvinyl alcohol derivative comprises photocrosslinkable groups.
  • Typical binders are water-soluble, film forming polymers.
  • Preferred binders are polyethylene oxide, polyvinyl alcohol, poly(2-ethyl-2-oxazoline), and polyvinyl pyrrolidone.
  • Polyvinyl alcohol must be sufficiently hydrolyzed so that it is soluble in water. Polyvinyl alcohols which are about 60-100% hydrolyzed are preferred. A molecular weight of about 10,000 to 186,000 is preferred. Polyvinyl pyrrolidone in the molecular weight range of about 10,000 to 360,000 may be used to advantage. Polyvinyl pyrrolidone is discussed in Chapter 21 Of Handbook of Water-Soluble gums and
  • the support may be any suitable material which has the necessary stiffness and dimensional stability.
  • Polyethylene terephthalate is preferred.
  • a removable support is required for preparation of a surprint proof.

  • the element was subsequently washed with tap water by holding the colored element under a water stream to wash off the non-exposed areas of the photosensitive layer. After drying with a hot air gun, the element showed a sharp magenta-colored image with a color density of 1.1 and tonal range of 1-98% dots for a 150 lines/in (60 lines/cm) screen. Color density was measured with a MacBeth RD 918 reflection densitometer which measures the amount of light reflected by a solid image.
  • Exposure was carried out as described in Step 3 of Example 1.
  • the exposed element was toned with magenta toner using an ATM II automatic toning machine (E. I. du Pont de Nemours and Co., Wilmington, DE).
  • the toned element was washed out and evaluated as described in Step 4 of Example 1.
  • the resulting image had a color density of 1.4 and a tonal range of 0.5-97% dots.
  • the coating solution was prepared as described in Example 8, Steps 1 and 2, except that Zonyl® FSO-100 (0.02 g). was added to the coating solution (20.0 g).
  • the photosensitive element was prepared following the procedure of Example 11.
  • the photosensitive layer coating weight was about 40 mg/dm 2 .
  • Exposure, toning, and washout were carried out as described in Example 9 except that exposure was carried out for 40 sec.
  • the resulting image had a color density of 0.8 and a tonal range of 2-90% dots.
